Using Temperature Sensors for Surface Mounting

For quite some time, ABB has been supplying surface mount sensors for non-invasive temperature measurement as well as temperature sensors for classic use with thermowells. Currently, these include the SensyTemp TSC400 series industrial thermometers for universal use in pipping and vessel construction and also in machine and system conduction generally.

Additionally, special versions of the SensyTemp TSP100 and TSP300 sensors are available for process measurement technology.

SensyTemp TSP341-W Sensor from ABB

The SensyTemp TSP341-W (‘W’ stands for ‘wireless’) was introduced in 2014 and is the first new-generation sensor from ABB from the line of sensors for non-invasive temperature measurement in process technology. This surface-mounted temperature sensor is also especially suited for subsequent extensions in industrial facilities due to the WirelessHART communications protocol.

The TSP341-W has the option of being supplied with an Energy Harvester. This allows for fully autonomous operation by recovering the required electric energy form the temperature difference between the process and ambient temperatures.

The TSP341-W successfully underwent its first test in an extensive pilot installation in which sensors were installed without needing to interrupt the process of production. Important insights were gained, for example the influence of the mechanical design of the sensor at the test point, different flow conditions and different types of insulation.

Conclusion

This enabled measurement accuracy of the installation to be improved from an initial value of several Kelvin to approximately 1 K and the cutting of the response time by 75%. This meant that the performance of a classic invasive temperature sensor had almost been reached [1]. The TSP341-W sensor has been successfully implemented worldwide with this level of performance.
